cheers psy,I actually leave the case open all the time as where i live(north queensland,australia) it's damm hot and humid most of the time :? ) plus it seems to happen only every ferw minutes,then fine then slow then fine and so on,I'm startin think maybe my hard drive is maybe on the way out(im not sure if that would cause it but its seems posible) but Im gunna give the heat sink a clean and put some fresh compound between the CPU and heatsink just in case(prob not a bad idea anyway)

cheers ill let ya know how it went,cheers for the tip
